I'm unclear on the purpose of the pin. Does it fix the extension to the upper so it doesn't rotate?
A fix is in for the S&W AR-10 barrels

New M&P 10 Owner
I sure wish I would have found these posts BEFORE I bought one of S&W's attempts at the AR-10 platform. My bad, I should have done a little more research. I swore off S&W back in the 90s and it doesn't appear things have changed much. It's too bad that S&W doesn't feel the need to provide customer service that is on a par with most of the rest of the industry. Not selling parts for an AR platform is ridiculous. Especially when the rifle is made to proprietary specs. At the very least S&W should offer upper receivers and barrel extensions.

On the bright side, it's nice to know people are out there working on a barrel for this in case I ever do anything like leaving something inside my barrel when I try to force a bullet down the same path.

Watching this thread intently.
A nice accurate 20" bull barrel would be lovely to have installed.
Wonder if BHW will ship to New Zealand?

Replacement barrels from BHW
I could have sworn this thread was: "A fix is in for S&W AR-10 barrels". I guess if the M&P isn't an AR-10 platform then this thread must be misplaced! The M&P is obviously a rifle by definition as is every other long gun with rifled bore. Furthermore the M&P certainly has all the markings of being in the AR family, hence my reference to the AR-10 platform.
On a more pertinent note -
I contacted Black Hole Weaponry as to the possibility of having a barrel replaced on a M&P 10. Here is the reply that I received from Jason Allen yesterday:
Ken-
The issue with the M&P is the proprietary barrel extension.
I have built barrels for these rifles, but, the customer has sent me his upper and I have dis-assebled his existing barrel and used the extension.
So, in short, yes I can do barrels for that weapon but I'll need your old barrel to do it.
Let me know!
Thanks!

Now if only S&W would offer reasonable customer service....

Yep. S&W makes M&P-10s. Armalite makes the AR-10
Yep
But the AR isn't a platform and it's especially not a weapon's platform. Aircraft, boats, vehicles, tanks and anything else that carries a weapon into battle or other situation are weapon's platforms. The shooter is a platform. The rifle is not a platform- unless you bolt a bunch of crapola to it. Then it becomes a crapola platform and only if carrying the crapola into battle is it's primary mission, not shooting

The AR10 (Armalite Rifle, Model 10) is specifically made by Armalite and it is their proprietary design. The M&P10 shares only the general shape and ammunition of choice. The M&P10 is based of the Stoner and DPMS design (SR25/LR308) with their own twist to it. When looking for parts that will fit it, AR10 parts will not fit but quite a few SR25/LR308 parts do. That is why people make a point of the distinction. Not because they have anything in particular against Armalite.
Calling all 308 ARs an AR-10 is like calling all pony cars a Mustang

Yes, the barrel extension (index) pin aligns it to the receiver.
Thanks for showing this!!!!

This is great news! I must admit, though, being an occasional shooter I have had ZERO problems with my '10 and love shooting it!!! I don't reload (yet) but have followed other members comments and achieved successful results by listening and (for the most part) following advice. I also maintain my weapon per factory recommendations (after 8+ years as an 0311 I can and do know how to clean/lubricate parts and properly utilize and store/ect. My weapons). I have as yet to have an ftf or accuracy issue. If you want a tack-driver build an M-40 (clone) or equilivant clone and whoop it up! I friggen LOVE THIS RIFLE!!! I also recently purchased a M&P 15 PSX piston AR that has also operated without issue. My only regrettable S&W experience has been the sale of my old model-29 w/8" barrel. I kick myself constantly for selling that! One hell of a hand cannon! I wonder if Mr. Eastwood got to keep his "Dirty Harry" '29? I say keep up the good work S&W! I have trusted my and my family's defense to your products for a lifetime and that ain't gonna change! Great posts on this forum btw! All of this free experience is greatly appreciated!!!

MP-10 BARRELS!
I too have heard of the great barrel debacle! And as a former recent military vet has told me this is what you get when you unpack a new weapon and go out and ram 50 rnds to whatever thru her in 50 secs. without a cool down a barrel cleaning and lubing every 5 to 10 rnds after slamming the biggest capacity mag found in it! we laughed! Proper brake- in applies to all weapons. I've had my 10 since it first came out. broke it in with sanity! Amd it's as smooth as glass after, I'll say ...... to many mags to count! I've gotta feeling there's some macho testosterone neglect going on here! And when they give you a recommended load or grain to use? Its just that!

Anyone done a BHW barrel replacement yet?
How would you also test the bolt for strength after a barrel split?
There is one not far from me for a decent price with a split barrel... Might have to get it as a spare

If it's cheap and a complete rifle, I'd get it for the spare parts. Heck, you can build another upper.
M&P 10 Barrel
For all who may be interested...
I sent my complete M&P10 upper to Black Hole Weaponry. I was looking for a 7mm-08 heavy barrel. Here is what we found:
The bolt and barrel extension are proprietary to S&W. BHW found that a DPMS BCG and extension will work in the S&W upper receiver.
I elected to retain the S&W BCG and extension. BHW removed the extension an put it on the new barrel.
I went with a 24" barrel which required a new gas tube since the factory gas tube is a proprietary length also.
BHW built an incredible barrel for me.
I put the gun back together tonight and have a few issues...
I bought a CMC drop in trigger that I was told would fit the 10. It does not fit due to the ambidextrous bolt release on the right side.
I had a Geisle trigger in an AR 15 and swapped them out. This trigger fits and works in the 10.
The only issue I have now is the bolt release will not hold the bolt open in this configuration. I have not tried to swap out to the factory trigger yet to see if this will fix the problem. I will update when I do.
I have not shot the gun yet but will report on that this weekend.
BHW was great to work with and I highly recommend them for your barrel needs.

Awesome AWESOME news!!
Seriously great find! I was already gonna source a BHW barrel for my SPR build, but will obviously use these guys for my future M&P10 changes too. This info seriously makes future barrel swaps as trivial as they are for the AR15 platform. However, I'd still like to hear someone with this configuration successfully operating their M&P10 with the DPMS BCG and barrel extension.
Really excellent info. Thank you!
